Kyrsten Sinema says in a legal document that she had a romantic relationship with a member of her security detail, but her lawyer argues a lawsuit seeking damages against her should be dismissed. The guard's ex-wife is suing the former Arizona senator in North Carolina federal court for what's called “alienation of affection” by breaking up their marriage. Sinema says her relationship with Matthew Ammel ”became romantic and intimate" in May 2024. Sinema denies contacting him in North Carolina where the couple lived while the marriage was still intact. Her lawyer says her conduct doesn't connect her to the state in a meaningful way.
